i used the font from this design : https://www.printables.com/fr/model/884318-number-hause-60-numero-casa-60
you can easily print it using 2 colors like i did, even with a single extruder printer (like ender 3), you just need to change the filament when the "0" starts being printed
hope you'll like it
